Do not run tests with sudo

So we setup our action with go 1.17.
However the ubuntu machine sets up an earlier version of go by default (1.15)
When we add 1.17 it is added for the non-root user only.
Our action was running `sudo ... make test` so it is running with 1.15
and caused annoying failures.
